Every Afghan ruler in the 20th century was assassinated, lynched or deposed. The Communist government tried to tear down the old structures of mullah and khan; the anti-Soviet jihad set up new ones, bolstered with US and Saudi cash and weapons supplied from Pakistan. There is almost no economic activity in the country, aside from international aid and the production of illegal narcotics. The Afghan army cannot, like Pakistan’s, reject America’s attempt to define national security priorities; Afghan diplomats cannot mock our pronouncements. Karzai is widely criticised, but more than seven years after the invasion there is still no plausible alternative candidate; there aren’t even recognisable political parties. –“The Irresistible Illusion,” Rory Stewart, The London Review of Books

In its 2007 report, the Intergovernmental Panel on Climate Change (IPCC) forecast a sea level rise of between 19 and 59 centimetres by 2100, but this excluded “future rapid dynamical changes in ice flow”. Crudely speaking, these estimates assume ice sheets are a bit like vast ice cubes sitting on a flat surface, which will stay in place as they slowly melt. But what if some ice sheets are more like ice cubes sitting on an upside-down bowl, which could suddenly slide off into the sea as conditions get slippery? “Larger rises cannot be excluded but understanding of these effects is too limited to assess their likelihood,” the IPCC report stated. Even before it was released, the report was outdated. Researchers now know far more. And while we still don’t understand the dynamics of ice sheets and glaciers well enough to make precise predictions, we are narrowing down the possibilities. The good news is that some of the scarier scenarios, such as a sudden collapse of the Greenland ice sheet, now appear less likely. The bad news is that there is a growing consensus that the IPCC estimates are wildly optimistic. –“Sea Level Rise: It’s worse than we thought,” Anil Ananthaswamy, New Scientist

More than once in my travels in Alaska, people brought up, without prompting, the question of Palin’s extravagant self-regard. Several told me, independently of one another, that they had consulted the definition of “narcissistic personality disorder” in the Diagnostic and Statistical Manual of Mental Disorders— “a pervasive pattern of grandiosity (in fantasy or behavior), need for admiration, and lack of empathy”— and thought it fit her perfectly. When Trig was born, Palin wrote an e-mail letter to friends and relatives, describing the belated news of her pregnancy and detailing Trig’s condition; she wrote the e-mail not in her own name but in God’s, and signed it “Trig’s Creator, Your Heavenly Father.”–“It Came from Wasilla,” Todd S.

“He could be one of a million beach-bound, black-socked Florida retirees, not the man who, by some odd happenstance of life, possesses the brain of Albert Einstein — literally cut it out of the dead scientist's head.”
